Do You Know?
DNA is the basic building block of life. It carries all the information that makes us who we are. Tap to read more.
Genetic Blueprint
DNA carries the instructions that living things need to grow, develop, and function. It is responsible for passing on traits through generations.
Structure
DNA is shaped like a twisted ladder, called a double helix, with two strands connected by pairs of chemicals that store genetic information.
Location
DNA is mainly found in the nucleus of cells. It is tightly packed into structures called chromosomes, and can also be found in mitochondria.
Heredity
DNA carries the information that determines traits like hair colour, height, and eye colour. It is passed from parents to their children.
Replication
DNA is made of four chemical building blocks called bases: adenine, thymine, guanine, and cytosine, which combine in different ways to form the genetic code.
Base Pairing
In DNA, the bases always pair up in a specific way: adenine with thymine and guanine with cytosine, creating a stable structure for storing genetic information.
